I am designing post-tension anchor system to repair a dam. I am planning to use the “DYWIDAG post-tension system using bars”
This is with a bar length of 40’ to 50' and will be anchored to concrete with approximately 110kips applied load on the rebar. My intention is to use cement grout. To determine my bond length I need to know the working bond stress in the interface between the concrete (assuming 3000psi) and the bonding material (high strength grout). Could you please provide me with this info. or catalog. And any other suggestions or comments are welcomed.
Thanks a lot
